Serial No. 413,409.

within the coupler on a horizontal axis 13 and has two arms 14 and 14:, one extending back of the tail of the knuckle, and the 1 other, 14, extending over the path of the vertically movable lock 5 so as to be engaged thereby. When this look is lifted by the upward movement of the lifting arm 7 it first releases the knuckle, leaving the latter free to be swung open, and then, in its further upward movement, the head of the lock 5 engages the arm 14 and rocks it on the axis 13, moving the arm 14 forward and throwing the knuckle into open position.

Within the scope of my invention as defined in the claim the parts may be modified in various ways since What I claim is:

A coupler head having a pocket depending below its bottom wall, a locking member having a portion extending downwardly into the pocket and having a support on the floor of said pocket when in the locked position, a lifting device extending upwardly into said pocket and into position to engage the lower end of the locking member, and a knuckle-opening member pivoted in the upper portion of the coupler head and arranged to be engaged and operated by the locking member when the latter is raised by the lifting member, substantially as de- To all whom it may concern:

Be it known that I, CLINTON A. TOWER, I of Cleveland, Cuyahoga county, Ohio, have t invented a new and useful Improvement in Car-Couplers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 shows my improved coupler in horizontal section; Fig. 2 is a vertical longitudinal section on the line II-II of Fig. 1; Fig. 3 is a vertical cross section on the line III-III of Fig. 2; Fig. 4 is a section similar to Fig. 1, showing the knuckle unlocked and open; Fig. 5 is a vertical longitudinal section on the line VV of Fig. 4; and Fig. 6 is a vertical cross section on the line VI-VI of Fig. 5.

In the drawings, 2 represents the couplerhead, having a horizontally swinging knuckle 3 mounted on a vertical pivot pin 1.

5 is the upwardly and downwardly movable lock which is mounted for vertical movement within a recess 6 of the drawhead and has a downward. extension 5 adapted to rest on the floor of the coupler when the device is locked. This lock is operated by an upwardly movable lifting arm 7, preferably made integral with and forming part of a lever 7 which is pivoted scribed. at 8 to the shank of the draw-bar and may In testimony whereof, I have hereunto bi operatedhby a yoked!) moulnted 3n afrock set my hand. saft 10wichextenstotesieo the car and is preferably journaled in a bracket CLINTON TOWER 11 depending from the carry iron 12.
